Dynamic mathematics with GeogebraDr Christian Bokhove@cb1601ejC.Bokhove@soton.ac.ukSouthampton Education School
Who am I? – Christian Bokhove, Netherlands – Teacher maths & computer science secondary school „98-‟12 – ICT & maths projects and PhD Disclaimer – We do not favor one software or the other …but we have to choose one – Be critical about all software and hardware – www.geogebra.org
And now… Who knows geogebra already? Can you describe geogebra in your own words? Short introduction
What is GeoGebra? Dynamic Mathematics Software For Learning and Teaching in Schools Geometry, Algebra and Calculus Freely available from www.geogebra.org
Examples of Using GeoGebra Visualizing students can “see” abstract concepts Representations students can make connections Experiments students can discover mathematics
Multiple Representations GeoGebra: Bidirectional Connection Symbolic ⇔ Graphics Examples – Coordinates ⇔ Point in Coordinate System – Circle„s Equation ⇔ Circle drawn in Coordinate System – Function„s Equation ⇔ Graph of Function
Educational Principles Student Activity Modeling Multiple Representations Experimental and Guided Discovery Learning – Great to show you everything but better off discovering yourselves!
Hands-on activities Do several activities Choose from the worksheet(s), on Blackboard (or paper) – Work from 1 to 5 – Then choose what you like from 6 onwards – Main goal: learn to use geogebra Want to learn more?
